Beit known that I, Gnome H. DAY, a

citizen of the UnitedStates, residing4v at in thecounty of vWorcester and.

Southbridge, State of Massachusetts; have invented certain new and useful Improvements in .Temples, of which the following is tion.

This invention relates to improvements in temples or members for retaining ophthalmic mountings on the face, and has particular reference to an improvement in that type of temple in which part is formed from metal and part from shell,` lar non-metallic material. A

The leading object of thepresent invention isthe provision of .animproved joint between the said metallic and non-metallic 4specific details fis . infor-cement of parts which shall firmly and satisfactorilyconnect said parts.

A further object of the present invention is the provision 4of` an improved manner of unitinp'` the various parts so as tolpresent a neat and. attractive structure and t0 rigidly Vand lirmlyunite the parts and prevent' j any liability of breakage Vat the joint by remember.. D Another object of the present invention is thc provision-of an improved manneror process of so joining will be securelyand satisfactorily held and the `finished article will be braced or reinforced and `also locked a'gainost accidental.

.loosening movement, substantially as illustrilte'd.. 4 o

In the drawings, the numeral 1 desig- Yrepresents a similarplan view pf -said part.

natos the usual temple side formed of round while the numeral 2 denotes a corres )ending part formed from flattened stock, t 1e wire being provided in either event with one end of the head portion 3 of able construction to engage the temple dowel and pivotally connect the side and lenses..

In Fig. I, I have shown the portion 1 as of round stock and in a number of other figures of the ldranvings as at stock, it be ing understood that for pulp es' of the present invention it is immaterial `which type of stock is employed for the mam porf tion of the side.

Broadly described the essential features of the present invention and process consist in forming an interlocking joint between the metallic and non-metallie parts and in then surrounding this joint with a cap 0r ferrule member which shall reinforce the joint and shall tightly bind or hold the arts together.

More specifically considere the invention resides in the structure and process by which the metallic and non-metallic parts are 1ntcrcngaged or interlocked one with the other by relative lateral as distinguished from relative longitudinal movement, and in which the cap or ferrule is then slid along to overlie the joint and prevent lateral disengagement of the parts.

Referring to the drawings: In Rigs. IV and V, I have shown the side portion 1 as iiattened into the head 4, cut preferably with the bevel or diagonally extending face 5, from which depend the ear hook engaging teeth 6. It 1will be understood that` these teeth could be otherwise formed on 'the round wire than by flattening, but I preferably Hatten the material in order that it may more readily fit into a suitable slot 7 in the ear hook portion 8. In the case of the form shown in Fig. VI, and -in a number of the` following views, however, as is initially formed from flat stock, it is not necessary to forni the headfl by flattening, but merely to cut or otherwise produce on the head the teeth 6 for biting into the ear hook 8. y

In the several forms of the invention possessing these. teeth, in the preferred operation of my process I preferably form the diagonally extending ker or slot in ythe end of the ear hook of approximately the size to receive the head or terminal portion 4 of the m`ctallic side and thon by relative lateral shifting of theI parts suitably press or force the heat down into the korf so that the teeth 6 will bite into thc material of the ear hook 8.

It will, of course, be understood that if preferred notches may be` formed in the lower wall of the korf to receive the teeth so that they may accuratelyl fit together, but for ease of assembling I avc found that it is merely necessary-to form the korf and 'the two fingers 9 there other, I slip over hook 'as illustrated in the side 2 then relutivel forcibly shift the parts, when the teeth wil automatically bite into the kerf and securely interlock with the ear hook without the necessity of forming the receivin notches therein.

e genera. manner of assemblin the construction shown in Fi VIII, XI and XV is the same as that )ust described.

`InV the assembling, however, of the form shown in Fig. XLI preferably spread apart illustrated, slipping therebetween and subsequently pressing them inward so that they bite into opposite sides of the ear hook, while in the forni shown in Figs. IX and X the temple is split or kerfed and the terminus of the side suitably slipped thcreinto and the material of the ear hook subsequently pressed inward either under the influence of ieat, while the temple end is heated, or cold, and simply through the inuence of pressure to cause the material to expand in the bosses 10, interlocking with the aperture 11, to curely lock the parts together.

In any event, the parts having been suitably assembled with the head on the end of one interlocking with the material of the the parts the ferrule 12 shown in detail .in Fig. XX and preferably having the rectangular or elongated slot 13 fitting the correspondingly shaped portion of the temple'so that it is locked against the temple end rotation relative to the temple.

There 'are"several methods of `applying this ferrulcto obtain the desired result. The ferrule may either be initially slightly larger than the end of the ear hook or of approximately the size to receive the end of the ear Fig. XVIII for exam le, and may be slip ed over the parts an subsequently swage to cause it to become embedded in the material of the earthook section, thus compressing the material at the joint around the ead on the temple side, causin additional rigidity of the parte at this point, and em bedding the ferrule onto the ear hook portion tom'ake a substantiallyflush joint therewith, asihdicated in Fig.

As an alternative method I may turn or press a reduced portion onthe end of the non-metallic member, either plain to receive the ferrule, and decrease the amount of re duction necessary to rmly connect the parts, or may make a tapered endeportion as shown in Fig.,XXI, and then force the ferrulle thereover to obtain ``desired tightness of the joint.

As an example of a form of my construe tion in which additional swaging is ernployed to increase the tightness of the joint and su plement the 'gripping the form illustrated in Figs. VIII,.{ X,

or reduced down action of-tlrc Y teeth 6 1n preventing separating of the parta` by direct pull, I would direct attentie to length as shown best brace the parts 5 Ucad of modesti XXVI and XXVII, in which the feri'ule is formed with a circumscribing exterior groove 14, .the material biting down `interiorly into the non-metallic ear hook section and forming a sort of head on that section enbedded within the tubularend of the fer ru e.

Attention is also particularly invited to the construction as illustrated in Figs. VIII, and for example, in which it will be noted that in Fig. VIII by formation of the exterior 'groove at I4 in the ferrule the material of theferrule is caused to actually bite doivn into the material of the 'ear hook 8. while in Fig. VII a 'corresponding result, though less noticeable, has been accomplished by compressing the ferrule at the rear or open end 15 to a greater degree than at the closed or forward end, so that a long gradually tapering head is provided onthe ear hook section 8, said head being largest at vits forward end so that it is firmly locked within the ferrule, while at the same time the operation of swaging causes the forward part of the ferrule to firmly bite'into and j fric-tionalljY and mechanically interlock withV the side to preventforward movement of the side relative to the ferrule, the ferrule thus yhaving a locking engagement with both the' side 2 and the ear hook 8 independent of,theirinterlo'cking laterally opening joint. whereby the grip of thel ferrule onthe two parts whenproperly assembled is sutlicient to hold the 'parts together if necessarjr independently'of. tbe joint aforesaid'.

It will also he noted that the surrounding ferrule' bearsagainst the head of the metallic side, preferably at. dialnetricaliy opposite points and locks it against any bending movement relative to the non-mei allie portion, tending to cause a breaking or working loose of the joint. while the fitting of the' 'flattened head between the walls .of the hert in the endof the ear hook portion prevents absolutely any relative twisting of the parts. It' desired the teeth maiy he of sufiicient in Fig. XII for example to extend entirelj,T through the ear hook at certain points and Contact with the fel-rule at tb'tn opposite side: trom that on which they are introduced, thus enabling the ferrule to against relative angular bending or breaking' of the joint.

In. Fig. v XXII I have illustrated in per s|ieeti\'e.a very desiralile form of ferrule is `formed abone end 'which ineloses While the bod),

The com- `wherein the bod)r 15 with a tapering portion 16 the end oi the templeside 4 itself entirely ineloses the joint. plete joint as provided bi' Form of terroir is best illustrated 'in Fig. XXVI.

In Fig. XXVII I have illustrated that' form of the invention -Wherein the flattened he temple side is provided with parts against longitudinal Will be one of the parts fitsdown ment in the pth is improved assembling this form of the-invention the of the temple side is inserted into the slot' in the end of the ear hook rule is then placed in position over the joint and pressure brought to bear upon the same whichv Willgroove the ferrule as shown at 18 forming a beading 19 the non-metallic material and retains the same against any longitudinalfmovement with respect, to the temple The pressure upon the ferrulewill also force the material of the ear hook into the elongated slot to assist in retaining the movement. It

noted that the end of the ferrule Vis portion, the' fer;

whichv bites into of the ear 'hookpressed firmly into the material of the ear hook to provide a substantially smooth joint.

From thisit will be apparentthat by the use of the ferrule as shown in Figs. XXII, XXVI, and XXVII a joint is provided which not only-.forms a neat joint but one wherein the parts are securely held against'any relative movement since the i`nter-engagen1ent of the head of the side in the slotot the ear hook prevents parts,4 the forcing or swaging of the ferrule around the joint binds the parts tightly -together 'and the engagementof both sides of the head with the ferrnle prevents relative binding of-the parts at the joint, this com ression also forcing the material of the llioolc into the eye of the head to interlock therewith and prevent relative'longitudinal Separation of the parts. while such separation is also prevented by the inter-` seen that I have provided a construction in which the parts have a firm interlocking connection one with the other. and in which into the other end in which ythe joint is reinforcedand the several' parts securelv bound and pressed together by means surrounding, and holding the joint. 4which means serve to loclrthe' parts against disengaging 'movedirec'tion of their `initial ,fitting together.- i

, It Will also be noted that the surrounding fer-rule bears against the headof the metallic side, preferably at, diametrically op of site points and locks it against anybendmg movement relative to the non-metallic portion tending to cause a breaking or Working loose of the joint. while 'the litting'of the Hattened head between the walls of the kerf in relative twisting of theA concealing the end of thc ear hook portion prevents absolutely any relative twisting ot' the arts. lf desired the teeth may be of su cient length, as shown in Fig. XII for example, to extend entirely through the car hook at certain points and contact with the ferrule at the opposite side from that on Whic theyl are introduced, thus enabling the ferrule to best brace the parts against relative angular bending or breaking of the joint.
